Z d vulmm 'if 'may concern.' v

Be 1t known that l, PETER lvnRsnN LANG- vLYKKE, a citizen of thegUnited States, and a tion of resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Spring Bed-Bottoms, of which the following isa specification. i

My invention relates to improvements in wire fabric designed, for use in spring bedbottoins, and has for its object the produca fabric of this character which will be of durable and economical construction and which will afford the desired resiliency for comfort.

A further' object is the production of a fabric as mentioned, which will be non-sagging in character, that is a fabric in which, when used in a bed-bottom, the occupation' of one portion of the bed-bottom will notV cause sagging of other portions of the bedbottom.

Other objects Will appear hereinafter. The invention consists in the combinations and arrangementsrof parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, forming a part of this specification, and in which,

Figure 1 is atop plan view of a bed-bottom, embodying the invention,

Fig. 2, a longitudinal section of the bedbottom,

Fig. 3, an enlarged transverse section of the bed-bottom, and

Fig. l,anenlarged fragmental plan View of a form of the construction designed to produce a non-sagging bed-bottom. Y

The preferred form of construction, as illustrated in the drawings, comprises a bedbottom consisting of a rectangular france5 and a fabric connected'therewith, said fabric being engaged at its ends with the upwardly extending flanges of angle irons 6 which form the end bars of. the frame. In the connection of the fabric lwith the bars 6, helical tension springs7 are employed, as is customary, which lend yieldability orresiliency tothe bed-bottom. y

The fabric comprises a plurality of spaced apart parallel longitudinally extending ca` bles, each' of which is formed of a'pair of co-extensive Wire strands 8. Said cables arek connected at intervals by transversely exkspaced-apart portions 8-8 tending links 9. The ends of links 9 engage with loops 10 which are formed at intervals in said cable, twisting-.the cable strands together at intervals to form substantially' unyielding eyes 10. 'In order to insure against unwrapping or unwinding of the cable strands through pressure applied Vat the eyes or loops 10 by the links 9, when the bed-bottom is in use, the cable strands at opposite sides of each said loops being produced by i eye are oppositely twisted, it being seen that with this arrangement asecure hitch or interlocking is effected at opposite sides of `each eye which will positively prevent un- 'wrapping or unwlnding of the cable strands.

At the same time, this peculiar twisting of the cable strands is very easily produced, inasmuch as the wires, in the formation of the cable, are turned first`` in one direction and then in the other, instead of continuously in one direction as is ordinarily done in twisting .two wires together, leaving parallel between adjacent eyes. The links at the longitudinal'edges of the fabric engage with perforated spring metal strips-ll, connectedat their' ends With the bar 6 in the same manner as the ends of the cables. .The-ends of the cable strands project into the adjacent ends of the springs, 7, as clearly seen in Figs. 2 and 4', to protect the same,said springs, at the same time serving to hold the strand ends against unWrap-v ping or untwisting.

lVhere it is desired to produce a non-sag-A ging bed-botvtorn, thatis one in which, when one portion lof the bed is occupied, the other portion of thebed-bottom will remain perfectly straight and horizontal Vand unaffected by the occupied portion thereof, the number of links 9 employed in the bed-bottom Will be reduced fifty per cent. so that the links at opposite sides of each cable Will be in staggered relation, as seen in Fig. 4.

'With this arrangement, it will be seen that the bed-bottom is renderedlaterally yieldable so that a sagging of or pressure applied to one side of the bed will not be transmitted to the other side or portion of the bed.

While I'have illustrated and described theprecisedtailsof construction setforth, but

' preferred forms of construction for carrying 105 desire to avail myself of such variations and kmodifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to'secure by Letters Patent is: l

l. A spring bed-bottom fabric comprising a frame, having end rails; a plurality of helical springs spaced-apart and'connected at intervals to each end rail; a plurality of spaced-apart parallel cables, comprisinga pair of wires twisted together at their ends and connected to said helical springs with the twisted ends of said cables contained within the coils of said springs and engaging the interior surface of the springs.

2. A spring bed bottom fabric comprising a plurality of spaced-apart parallel cables, eac'h extending substantially the full length of the bed bottom and each connected at its opposite ends to helical springs; links conneet-ingr adjacent cables together' at intervals; each cableJ comprising two wires spaced apart between eyes formed therein at intervals to receive the links, saideyes `formed byv twistingthe separated wires in opposite directions on each side of the respective eyes toan ,extent to-prevent separation of the wires Vwhen stress is applied thereto; the ends of said cables, beyond the terminal eyes separated to bear against the interior of the helical springs to prevent separation of the wires at the terminal twists. p

In Vtestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
